Rene Albert Bousher, 59, is charged with 4th degree assault and is being held at the Warren County Regional Jail. Media outlets and the jail spell the suspect's last name differently, with the media referring to him as Boucher and the jail as Bousher.

"Senator Paul was blindsided and the victim of an assault. The assailant was arrested and it is now a matter for the police," said Kelsey Cooper, state communications director for Office of U.S. Senator Rand Paul.

Senator Paul, a Republican in his second term, is an ophthalmologist from Bowling Green.
